TikTok owner ByteDance is pre-training a massive 10-trillion-parameter AI model to challenge Anthropic’s Mythos.
TikTok owner ByteDance just raised the stakes in the global tech race. Reports from the Financial Times indicate the company is pre-training a system massive enough to challenge Anthropic’s frontier Mythos model.
To put that number in perspective, this new model triples the size of Moonshot AI’s Kimi K3, currently China’s largest public model. ByteDance founder Zhang Yiming recently told his engineering teams to stop chasing quick wins and focus on building world-class infrastructure. This multi-month training run shows he meant every word.
Critics often argue that raw parameter counts matter less than slick fine-tuning and clean data. They have a point. Smaller, highly optimized models regularly punch above their weight. But when a company combines trillions of parameters with top-tier consumer distribution, the game changes completely.
ByteDance already dominates China’s consumer AI market. Its Doubao chatbot pulls in 324 million monthly active users, while its SeeDance video generator rivals the best tools coming out of Silicon Valley.
Placing a 10-trillion-parameter engine behind those products gives ByteDance an incredible advantage.
This mega-model will take three to six months to finish its initial training run. Yet ByteDance’s sheer ambition sends a clear signal across the market. Tech heavyweights keep spending billions to prove that bigger models still unlock entirely new capabilities while skeptics debate whether AI scaling has hit a wall.
